10904880-4	2000	The results revealed that only in buffered formalin-fixed tumor specimens, considering the most darkly stained cells, the PCNA-LI in all cases overlapped with T-LI.	Formaldehyde	43-51	proliferating cell nuclear antigen	Homo sapiens	122-126	
10904880-5	2000	Higher values than those observed with autoradiography were detected in PCNA values obtained after usual formalin fixation whereas no or faint PCNA staining was seen in material fixed in Bouin.	Formaldehyde	105-113	proliferating cell nuclear antigen	Homo sapiens	72-76
